Pond Klear Xtra is a natural pond treatment designed to clear green and murky water by using beneficial bacteria. With three times more bacteria than our original Pond Klear, it works effectively by binding particles together and sinking them to the bottom of the pond. Unlike other treatments that only temporarily address the issue, Pond Klear Xtra tackles the root cause, maintaining clear water by breaking down particles and preventing them from floating back up into the water column.
This treatment is suitable for both filtered and unfiltered ponds, though it may take a bit longer to show results in unfiltered ponds as the bacteria have more work to do. Typically, you’ll begin to see improvements within the first couple of weeks, with complete clarity usually achieved within three to four weeks. Pond Klear Xtra provides a long-lasting solution for clearer, healthier pond water.
